Fitness

All participants should have a modest amount of fitness. No extreme fitness is necessary, but the ability to hike 1-2 miles in some heat with some very easy scrambling while carrying all of your gear, food and water. All of the intended sites are accessible but may require some hiking and mild scrambling with no dangerous exposure.
